I have many slopes on my roof and 12 downspouts. That is why not much drains from the downspouts, I’m sure. I do have a spring in the front yard out by the road, but that is way down the steep hill where I rarely ever go.

Do you know much about electronic speed controllers? I have a 30k ohm pot that has went south, according to the flashing trouble code light. I can get an exact replacement from Hong Kong for $7, but 10-18 days delivery time. They do not offer expedited delivery at all. I want to bypass it, but do not want to damage the $600 electronic speed controller. I think I can do this, but don’t know much about the speed controllers and how they work. It is for my electric scooter.

The same part from the American replacement parts company want $57+ shipping. RadioHut has a 10k ohm universal fit for $3.65 in stock locally.

Now if I could get this part sent to Korea quickly, my wife could get it from K. to Houston PDQ. LOL

You probably need the exact replacement part, without looking at a schematic. I wouldn't replace a 30K with a 10K, not without knowing exactly what the math is on the rest of the circuit. I might try a 50K Ohm variable in there, though, if the pot isn't a voltage divider, too.

Lots of speed controllers are PWM controllers with a VCO controlling pulse width/duration. Once again, the schematic is the final word. Read the source, Luke. ;)

RadioHut has a 10k ohm universal fit ...

How about three of those in series, with a lot of duct tape to hold it in place?
